Chemistry Text Mining Suite

Accessing your chemical content with our text mining capabilities

There is a huge chemical space locked in various types of scientific literature, e.g. patents, journal articles, internal documents, etc. ChemAxon has developed a suite of chemistry text mining tools to extract chemical information from documents in multiple languages.

Structure to Name (S2N)

Naming allows the user to generate IUPAC names and traditional names from structures, or CAS registry numbers via Web service. Radicals, natural products, and peptide sequences are also supported.

Name to Structure (N2S)

Various types of chemical names can be converted to structures with Naming, including IUPAC names, systematic names, common names, drug commercial names, and CAS names. CAS registry number is also supported via Web service.

Asian Language Support

To accommodate the fast growing scientific literature in Asian languages, ChemAxon has released Chinese Name to Structure (CN2S) conversion since version 5.12. Japanese support is now available with version 6.3.

Document to Structure (D2S)

The core application is Document to Structure. Not only supporting all types of documents, it also applies text OCR and image OSR technologies to extract information from non-searchable PDF documents (e.g. chemical patents). Once structures are extracted, the location of each structure is also returned. All these features make D2S an excellent choice for text mining and patent analysis

Discover the hidden chemical knowledge in documents, regardless whether they are located on local computer, network share or in the Cloud (Google Drive, OneDrive, DropBox, SharePoint Online, Office 365). Find faster, respond faster, decide faster. ChemLocator is a web based search tool with the capability of using it on personal desktop machines.

We have set up Chemicalize, a free public website tool to extract chemical information from webpages and documents, run phys-chem calculations and check controlled substances. After processing, all structures and results can be interactively displayed and summarized for download. Please note that all information extracted will be public.
